Optical Photometric Monitoring of the Blazar OT 355 and Local Standard Stars’ Calibration

open access: yesUniverse
OT 355 (4FGL J1734.3 + 3858) is a relatively rarely studied but highly variable, moderate-redshift (z = 0.975) flat-spectrum radio quasar (blazar). With this work, we aim to study its optical variability on different timescales, which can help us to ...

The prevalence of Streptococcus equi subsp. equi carriers in the Netherlands

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Streptococcus equi subspecies equi (S. equi) carriers are thought to be important drivers for strangles outbreaks. Limited data are available on the prevalence of carriers in European horse husbandry settings. Objectives To estimate the prevalence of S.

Prevalence of insulin dysregulation in a sport horse population as determined by traditional and stall‐side testing

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background The prevalence of insulin dysregulation (ID) has not been investigated in sport horses. Stall‐side insulin assays offer convenience but need further validation. Objectives To determine the prevalence of and risk factors for ID in a sport horse population using an oral sugar test (OST) and assess agreement between stall‐side and ...

Impact of extended NAO buoyancy forcing on the subpolar North Atlantic and climate variability over the last millenium

open access: yes, 2007
We examine the impact of forcing a regional eddy-permitting ocean model of the subpolar North Atlantic with anomalous buoyancy fluxes corresponding to extended extreme states of the North Atlantic Oscillation (NAO).

Perinatal predictors of parenting stress trajectories during the first 3 years of parenthood: A Maternal and Child Health Handbook cohort study

open access: yesJCPP Advances, EarlyView.
Abstract Background Evidence of how parenting stress evolves during early childhood is limited. We aimed to identify parenting stress trajectories involving children aged 1 month to 3 years, and to determine their perinatal predictors. Methods Data were obtained from 3133 mothers in the Tokyo Teen Cohort (TTC), a population‐based cohort of children ...

A New Phase of Optical Activity of BL Lacertae in the Fall of 2024: Intra-Night Flux and Polarization Variations

open access: yesUniverse
BL Lacertae is not only archetypical of an entire class of jet-dominated active galactic nuclei, blazars, but also one of the most active and rapidly changing objects in this class.

Mediterranean overflow water in the North Atlantic and its multidecadal variability

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2020
The Mediterranean overflow water is one of the most important intermediate-depth water masses in the North Atlantic. To investigate its properties a pre-industrial simulation with the earth system model EC-Earth is used.

Spatiotemporal Changes and Climate Driving Factors of Compound Precipitation‐Temperature Extreme Events Across Global Land Areas

open access: yesInternational Journal of Climatology, EarlyView.
During the period 1901–2024, the dominant proportion of compound dry‐warm extremes in annual, June–July–August (JJA), and December–January–February (DJF) occurrences was the highest among the four types of compound precipitation and temperature extremes across global land areas, accounting for 40.1%, 50.3%, and 28.0%, respectively.
